A look at the twists and turns of bilateral relations between Ankara and Moscow during Vladimir Putin's presidency.
Presidential elections will be held in Russia on Sunday and election polls suggest Vladimir Putin will win once again.
During his tenure, relations between Turkey and Russia have taken many twists and turns.
Starting with the downing of a Russian jet by Turkey in November 2015, Ankara and Moscow's relations took a blow.
Moscow reacted by suspending visa-free travel for Turkish nationals while also imposing trade restrictions.

Subsequently, a series of official visits and telephone calls between both sides normalised relations.
